"She said, 'Well, I have a meeting to go to' and she started getting upset," school director Antonietta Schneider said.

Schneider said Uriniuk wouldn't take no for an answer.

"She bit my arm. And I was kind of in shock and I said, 'Jessica, you just bit me', and she proceeded to scrape my face, pull my hair and she was hitting me," Schneider said.

"It took me a couple of seconds. 'Is that really happening? Is it really in the doorway? Was that really a parent? And then I stepped in to try to break it up," witness Jill McMahon said.

From her classroom, a teacher heard the shouting and screaming and came out here she said she couldn't believe what she was seeing at the front door.

"I saw some of the hits. I saw the bite. The way she was screaming, she had her by the hair at points, so that's when I was trying to separate them too, she reached around me and grabbed my boss' hair," McMahon said.

"She kicked me in the thigh, and then she kicked me in the bladder, and at that point, I fell because the pain was so intense, and my staff came out and took her off of me," Schneider said.

Photos helped the district attorney decide to file battery charges.

"So shocking to me that we've gotten to this point where parents, people don't want to follow rules and they want to get their own way and something like this could actually happen," Schneider said.

The school director suffered bruising to her internal organs and was treated at a hospital.

Uriniuk was arrested and is charged with battery and disorderly conduct.
